The fabric that is formed on looms of this type have at leastone selvage with a fringelike extension and in particular the inventionrelates to a mechanism which is adapted to turn these fringe endsinwardly to a position where they are beat-up into the fabric.

The tucking in of filling yarn ends for beat-up into the fabric has inthe past presented many problems that have made it difficult to form asatisfactory and acceptable smooth selvage at the fabric edge, and toadapt and set up a mechanism for this purpose which would perform itsintended function in positive manner. I

A few of the prime problemslwhich were quite troublesome can beattributed to nonuniform lengths of filling yarns and the inability tosuccessively control each individual yarn end by means for receiving andholding it prior to its insertion back into the warp shed. Additionallyloss of direct contact with the yarn resulted in failure of certainyarns to be tucked in and gave the fabric an appearance of inferiorquality.

A further problem was that of tension on the filling yarn. If thefilling is released at the side of the shed under too little or toogreat a tension, controlling its end is practically impossible.Excessive tension can cause a snap back of the yarn after its releasewhile too little tension can result in a shorter pick which fails to beheld and then acted upon by an inserting member.

The selvage forming apparatus according to the instant inventionprovides a substantially improved device and method of forming atucked-in selvage on shuttleless looms and by which the problemsdescribed above have been overcome.

- SUMMARY OF THE INVENTION The selvage forming apparatus of the presentinvention utilizes a plurality of harness controlled selvage threadsdisposed in spaced and parallel relation with the warp threads and theyare adapted to receive and hold the end of filling yarn after itsrelease by a carrier member. Yarn gripping, severing and insertingelements form a part of the apparatus and are movable by cam means topositions to act upon the end of filling yarn being held by the selvagethreads.

The yarn is gripped at a point intermediate the edge of the fabric andthe selvage threads where it is held and then severed adjacent to thegripping element. The gripping element is then lowered by a further cammeans to a position to present the end of yarn to the inserting elementwhich withdraws said end from the gripper and inserts it into a reopenedwarp shed for beat-up with the next inserted length of filling yarn.

It is an object of the invention to provide an improved means and methodfor forming a fabric selvage in a loom of the shuttleless type.

A more specific object of the invention is to provide a mechanisrnadapted to function solely by mechanical means for controlling the endsof filling yarn in shuttleless looms to form a smooth selvage at theedge of the fabric.

DESCRIPTION OF THE PREFERRED EMBODIMENT Now referring to the figures ofdrawing enough of a shuttleless loom is shown in FIG. 1 to serveas'a'ba'sis for a detailed description of the invention applied thereto.

In FIG. 1 the forward upper left hand end of a shuttleless loom is shownand among the various parts thereof there is shown a portion of theframework at 10, the left hand tape wheel housing 11 from which extendsthe usual tape guide 12. The filling extending carrier is depicted bynumeral 13 and as is well known to those conversant in the weaving art,said carrier is fixed on the end of a tape 14, which in the performanceof its intended function is caused to be wrapped about and unwrappedfrom a tape wheel (not shown) that is oscillatably driven within thehousing 11. A plurality of warp yarns are depicted in FIG. 1 by numeral15 and by means of the usual harnesses (not shown) form warp sheds 16(FIGS. 8, 9 and 10) into which a filling yarn 17 is inserted.

The loom reed is shown at 18 and provides the conventional means forbeating-up the filling yarns to form the fabric identified by numeral19. The left hand temple is shown at 20 and serves to guide the fabric19 as it is formed in a known manner.

The selvage forming apparatus according to the invention is identifiedgenerally in FIG. 1 by numeral 21 and includes a support housing havinga base portion 22 with upwardly directed sidewalls 23 and 24. Thissupport housing, as shown disposed shaft 28. Intermediate the standards26 and 27 shaft 28 has assembled thereon the hub portions of threesingle armed levers which are depicted by numerals 29, 30 and 31, andthe arms thereof by numerals 32, 33 and 34, respectively.

Immediately adjacent to the standards 26 and 27, sidewalls 23 and 24 areprovided with integrally formed bearing support housings 35 and 36having cap members 37 and 38, respectively, assembled thereon by meansof screws 39.

A cam shaft 40 is rotatably supported by the bearing support housings 35and 36 and as shown in FIG. 1 is caused to be rotated in the directionof the indicating arrow 41 by means of its connection as at 42 to a gearreduction box that is identified by numeral 43. This gear reduction box43 is driven by any suitable source of power on the loom by means of ashaft 44 which in the present case is connected in driving relationshipwith the looms cam shaft (not. shown).

That portion of the cam shaft 40 which traverses the distance betweenthe bearing support housings 35 and 36 has fixedly assembled thereon forrotation therewith four cam members identified by numerals 45, 46, 47and 48 (FIGS. 1,2,3 and 4). As shown in FIGS. 2 and 3 cams 45. 46, 47and 48 are fixed on cam shaft 40 by means of a key 49 and set screws 50.

A filling yam gripping and a severing device are depicted generally inFIGS. 4, 5, 6 and 7 by numeral 51 and are carried on a common supportbracket 52 which depends from the end of a bar member 53. Supportbracket 52 is attached to bar member 53 by means of bolts 54 and nuts55. Bar member 53 extends for substantially the full length of thesupport housing and is guided in a slot 56 (FIG. 1) provided in a guideblock 57 which interconnects sidewalls 23 and 24 of said housing at itsinner end or that end most remote from standards 26 and 27. FIGS. 2, 3and 4 show the guide block attached to the support housing by means ofcap screws 58.

That end of bar member 53 opposite the end from which the supportbracket 52 depends is pivotably connected to the arm 32 oflever 29 as at59 (FIGS. 1 an 4.) Ann 32 of lever 29 has a cam follower 60 rotatablyassembled to the side thereof at a point intermediate its ends which bymeans of a coil spring 61 is adapted to maintain contact with the outerperiphery of cam member 45. One end of this coil spring 61 is attachedto the guide block 57 by means of a screw 62 and the opposite end isattached by means of a bolt 63 to the bar member 53 at a pointintermediate its ends (FIG. 4).

Rotation of cam member 45 acts upon cam follower 60 so as to pivot arm32 of lever 29 thus causing the bar member 53 to reciprocate. Thisreciprocation movement carries the filling yarn gripping and severingdevices toward and away from a position to act upon the end of aninserted length of filling and will be more fully described hereinafter.Additionally, this movement is effective in causing the filling yarngripping and severing devices to be actuated by a fixed cam 64 that isdisposed above and relatively close to said devices. In FIGS. 1, 2 and 4a cam support bracket 65 is shown assembled to sidewall 23 of thesupport housing by means of cap screws 66. Extending angularly upwardlyand away from the support housing the upper portion of the cam supportbracket 65 carries a pair of horizontally disposed stud members 67 and68 (FIGS. 1 and In spaced relation to the cam support bracket 65 thestud members have the fixed cam 64 assembled thereon by means of nuts 69and 70.

FIGS. 4,5, 6 and 7 show how the fixed cam 64 is caused to actuate thefilling yarn gripper and severing devices. The gripper consists of aplunger rod 71 that is guided by vertically aligned apertures providedin a pair of integrally formed bosses 72 and 73 disposed on the side ofthe common support bracket 52. A coil spring 74 assembles on the plungerrod intermediate the bosses 72 and 73 and by means of a collar 75 saidspring is partially compressed so as to bear against the upper side ofboss 73. This spring 74 provides a biasing force for the plunger rod 71which continually urges it in an upward direction and maintains theupper end thereof in a position to be acted upon by the fixed cam 64 asthe gripping device is caused to reciprocate with bar member 53.

The lower end of the plunger rod 71 terminates in the form of alaterally extending foot 76 and in timed relation to the weaving cycleis caused by the cam 64 and spring 74 to first move away from theunderside of boss 73 and thence into engagement with it. This motionopens the gripper to receive the filling yarn and then closes it to gripsaid yarn.

The severing device is also actuated by the fixed cam 64 and in the samemanner as the filling'yarn gripping device. The severing device includesa plunger rod 77 that is guided for reciprocating movement in spaced andvertically aligned apertures. The lower aperture is situated in aforwardly extending foot 78 which forms a part of the support bracket 52and the upper aperture is situated in bar member 53 adjacent the pointof attachment of said support bracket. A coil spring 79 is positioned onthe plunger rod 77 intermediate bar member 53 and the foot 78 and bymeans of a collar 80 said spring is partially compressed so as to bearagainst said foot 78. This arrangement provides a biasing force for theplunger rod 77 so as to continually urge it in an upward direction andby means of a second collar 81 immediately adjacent to collar the limitof movement of said rod can be controlled.

The lower end of the plunger rod 77 is pivotably connected to theforward end of a cutting blade 82 the latter of which is pivotablyattached intermediate its ends to the lower side of the support bracket52 by means of a screw 83 (FIGS. 5, 6 and 7).

The filling yarn gripping and severing devices are so arranged thatlongitudinal movement of the bar member 53 in the direction of theindicating arrow 84 (FIGS. 1 and 4) first causes cam 64 to actuate thegripper device and thence the severing device which cuts the fillingadjacent to the gripper. The filling yarn 17 after its release by thefilling extending carrier 13 is caught and held by a plurality ofseparate selvage threads 85 (FIGS. 1, 10 and 12) which are controlled ina known manner by harness means not shown. In FIGS. 10 and 12 thesevered ends of the filling yarn are depicted by numeral 86 and areshown being held by the selvage threads 85. As the selvage threads areadvanced they pass through a guide wire 87 (FIG. 4) which is attached tothe side of the support bracket 65 by means of a screw 88. This guidewire maintains the advancing selvage threads 85 in spaced relation tothe edge of the fabric and they are then guided with the severed ends offilling yarn 86 through a rotating twister sleeve 89 (FIGS. 11, 12 and13). This twister sleeve has a centrally disposed aperture 90 throughwhich the selvage threads 85 with the severed ends of yarn 86 pass andthe diameter thereof is such that said severed ends are in frictionalcontact with the walls of said aperture. With the twister sleeverotating continuously, the frictional contact of the severed ends withthe walls of the aperture 90 is sufficient to slightly twist the selvagethread in the area of said twister sleeve so as to assure holding saidsevered ends of yarn.

The outside diameter of the twister sleeve 89 is recessed as at 91(FIGS. 11 and 12) and provides a tracking area for rotating said twistersleeve by means of an endless belt 92. The twister sleeve 89 isrotatably mounted in a hub 93 that forms an integral part of a bracketmember 94 the latter of which attaches to the sidewall 23 of the supporthousing by means of a cap screw 95. As shown in FIGS. 11 and 12 thebracket member 94 rotatably supports a pair of spaced idler pulleys 96and 97 about which the endless belt 92 is adapted to pass. The endlessbelt 92 is also in driving engagement with a pulley member 98 that isfixed on and which is adapted to rotate with the cam shaft 40 therebyproviding the means for continuous rotation of the twister sleeve 89.

A means is provided for lowering the bar member 53 so as to permit thefilling yarn gripping device to move the end of filling yarn heldthereby to a position for presenting it to the inserting member thelatter of which will be more fully described hereinafter.

This means for lowering the bar member 53 is controlled by cam member 46and the single armed lever 30. As shown in FIGS. 1 and 4, the arm 33 oflever 30 extends in a generally horizontal plane above cam member 46 andhas a cam follower 99 rotatably mounted on the side thereof and at apoint intermediate its ends. This cam follower is adapted to maintaincontact with the outer periphery of cam member 46 by means of a coilspring 100 which by means of a bolt 101 attaches to the end of arm 33.Extending downwardly the opposite end of spring 100 is fixedly attachedto the sidewall 23 (not shown) of the support housing. Bolt 101 alsoprovides a means for attaching one end of an adjustable connecting rod102 (FIGS. 1 and 2) to the end of arm 33. The lower end of connectingrod 102 is attached to the bar member 53 by means of the bolt 63 whichserves to anchor one end of the coil spring 61 that continually urgessaid bar member in longitudinal direction toward the position to permitthe yarn gripping and severing devices to act upon the filling yarn 17.

Cams 45 and 46 rotate continuously and are arranged in timed relation tothe weaving cycle so as to first cause the bar member and the grippingand severing devices carried thereby to move horizontally to a positionto receive, grip and thence sever the filling yarn adjacent its end.Continued rotation of these cams then brings a low point of cam member46 into contact with cam follower 99 thereby causing arm 33 to belowered by coil spring 101. As arm 33 is lowered connecting rod 102 ispushed downwardly and being connected to bar member 53 the latter iscaused to pivot in a like direction within slot 56 of the guide block57. The filling yarn gripping device is lowered simultaneously with thebar members 53 and the gripped yarn is then in position to be taken bythe inserting member now to be described.

The inserting member or so-called selvage needle is identified in FIGS.1, 8 and 9 by numeral 103. This selvage needle is of arcuatedconfiguration with the free end thereof defining a hook 104 forreceiving the filling yarn from the gripping device and thence insertingthe same into the warp shed. The opposite end of the selvage needle isadjustably carried in a support block 105 the latter of which is fixedon the end of a horizontally disposed rod 106. Rod 106 assembles in -atelescopic manner within the end of a second horizontally disposed rod107. By means of a clamping block 108 assembled on the end of rod 107the slotted end (not shown) of said rod can be compressed into clampingengagement with rod 106 at any position along the longitudinal extentthereof. Rod

107 extends through a flanged bushing 109 in the guide block 57 andforwardly thereof through an opening 110 provided in a second guideblock 111 which attaches to the base portion 22 of the support housingby means of cap screws 112 (one only shown in FIG. 3).

The end of rod 107 opposite the end to which the clamping block 108assembles has a sleeve 113 (FIG. 3) fixed thereon by means of a nut 114.The ends of this sleeve 113 are provided with aligned, radiallyextending and integrally formed web segments 115 and 116 between which adriving block 117 is positioned. This driving block is pivotablyattached to the lower end of the arm 34 of lever 31 by means of a bolt118 and nut 119 (FIGS. 1 and 3) and by means to be described providesthe means for longitudinal movement of rod 107. The web segmentsextending in close proximity with the sides of the driving block 117also permit the rod 107 to be oscillated while moving horizontally by afurther means yet to be described.

Arm 34 of lever 31 extends in a generally downward direction and hasrotatably assembled on the side thereof and at a position intermediateits ends a cam follower 120 (FIGS. 1 and 3). This cam follower isadapted to track on the outer periphery of cam member 47 andismaintained in contact therewith by means of a coil spring 121 one endof which attaches to arm 34 as at 122. The opposite end of spring 121 isfastened to a vertically extending stud 123 (FIG. 3) that is fixed bymeans of a cap screw 124 to the base portion 22 of the support housing.

Cam 47 is rotated in timed sequence with the weaving cycle and arm 34with its follower 120 is effective in reciprocating rod 107 to move theselvage needle 103 in a horizontal plane while simultaneously effectingoscillation thereof by the further means now to be described.

Rod 107 extends through a sleeve 125 that is supported for oscillatingmovement within the support housing. One end of this sleeve is guided ina recess 126 (FIG. 3) that is provided in the flanged bushing 109 andadjacent its opposite end is provided with a circumferential groove 127that provides a surface for its support by a yoked bearing member 128.Bearing member 128 is fixed to the base portion 22 of the supporthousing by a pair of cap screws 129.

As shown in FIGS. 1 and 2 sleeve 125 is provided with a longitudinallyextending recess 130 that serves as a track or raceway within which akey member, or as illustrated by the preferred embodiment, a roller 131is adapted to travel. This roller extends from rod 107 in a plane normalto the axis thereof and is attached to the latter by means of a bolt 132and nut 133. As shown in FIG. 3 that portion of the sleeve oppositerecess is also recessed for the greater portion of its length so as toprovide clearance for the end of bolt 132 and nut 133 duringlongitudinal movement of the rod 107.

That end of sleeve 125 opposite the end guided in recess 126 is beveledas at 134 throughout: its circumferential extent and a portion of thisbeveled end is provided with gear teeth 135 (FIG. 2) that define a bevelgear segment. Gear teeth 135 are in meshing relation with a second bevelgear segment 136 the teeth of which are integrally formed intermediatethe ends of an arm 137 that forms a part of a bellcrank lever generallyindicated in FIGS. 2 and 3 by numeral 138. This bell crank lever ispivotably attached to sidewall 24 of and within the support housing bymeans of a threaded stud 139, washer 140 and a nut 141 (FIGS. 1 and 2).A second arm 142 of the bell crank lever extends in a generally upwarddirection and has a cam follower 143 rotatably attached. to the upperend thereof. One end of a coil spring 144 is attached to the end of arm137 of the bell crank lever by means of a cap screw 145 and extendingupwardly the opposite end attaches by means of a cap screw 146 to theupper end of a spring bracket 147. Spring bracket 147 is in the form ofan upwardly directed bar the lower end of which is attached to side wall24 by screws 148.

Spring 144 is continually urging the bell crank lever 138 in a clockwisedirection as viewed in FIG. 3 and maintains cam follower 143 in contactwith the outer periphery of cam member 48. Rotation of cam member 48oscillates the bell crank lever 138 and the bevel gear segment forming apart thereof is effective in oscillating the sleeve 125.

As described herein rod 107 is caused to move longitudinally withinsleeve 125 and with the oscillating movement of said sleeve said rod isalso caused to oscillate therewith by means of its roller 131 trackingwithin the recess 130 of said sleeve. This compound movement carries theselvage needle inwardly toward the warp shed in timed sequence with theweaving cycle and rotates the needle so it will enter the shed and to aposition for receiving the filling yarn from the gripping device.

In operation the filling yarn is held adjacent its end by the separateselvage threads 85 after its release by the extending carrier 13. Thevarious cam members of the selvage forming apparatus are so arranged soas to move the devices controlled thereby toward their positions to actupon the end of the inserted length of filling yarn.

The gripping device is first opened and then closed to receive andthence grip the yarn. The severing device then cuts the yarn adjacent tothe gripper and the severed end is held by the selvage threads. Duringthis time the selvage needle is being advanced and rotated so as toenter the warp shed and to a position in close proximity with thegripping device. The gripping device is then lowered so as to presentthe yarn being held thereby to the hooked portion of the selvage needle.The selvage needle is again rotated which causes the yarn to be pulledfrom the gripper and during this rotating movement it carries the end ofyarn into a reopened shed for heatup with the next inserted length offilling yarn.
